Snap wire connector
The LUCAS snap connector, as shown in Illustration 33, is made up of four components.
Two are tubular sleeves, having pointed extremities, and which are soldered to the ends
of the two wires t6 be connected.
The third part is the centre split ferrule, into which
the two sleeves snap and the fourth component is a rubber sleeve which covers the whole
connector.
That rubber sleeve serves the dual purpose of insulating the various metal
parts and also preventing same from separation as the result of vibration.

Lucas snap connector
Part number 900269
One snap connector is used in the rear lamp wire and another is used in the wire con-
necting the regulator unit to the output side of the ammeter in the head lamp.
Two more are used in the headlamp interior (pilot lamp wires).
Terminals
All models have the POSITIVE battery terminal connected to " EARTH ".
The earth wires (two—one from regulator, the other from terminal of battery) and the
high-tension wire (on sparking plug end of wire from magneto to sparking plug) have
terminals of the solid sleeve type having an eye at the extreme end. To make such a
connection, it is necessary to bare the end of the wire for a ", pass the terminal over the
wire so that the bared end fully enters the reduced core of the terminal and then flatten
that part by either pinching in a vice or by hammering.
The two earth wires, mentioned above, are connected to the " earth " by securing them
to the seat lug (which is situated just under the saddle) by means of a nut, washer and a
screw. It is essential that the connections are kept clean and the screw must be kept
fully tight.
